From REST API and SDKs to langchain4j to fully managed cloud solutions to local integration with jlama and llama3.java of open source foundation models. In this session I will present architectures, ideas, hacks, and workarounds for integrating LLM with Java enterprise applications. I will illustrate the concepts with Java 21, Quarkus / MicroProfile code and integrate the latest Claude, ChatGPT, llama and AWS Bedrock models. Your questions will be given priority and answered interactively.

How to: run Java as a shell script, run a Java app without compiling, print an emoji, run an HTTP dev server, use libraries without compiling, colorful logs, access LLMs,run timer jobs, access the clipboard, implement a file watch, main in interfaces, easy file parsing (...) and ~100 other popular Java snippets from youtube.com/bienadam/shorts. No builds, no Maven, no dependencies, just javac and Visual Studio code.

"String.join() is 30% faster than Collectors.joining(), JMH not always necessary for high-level benchmarking, interfaces slightly faster than abstract classes but the difference is negligible, Quarkus requires no installation - just use the POM file, Quarkus tests are integration tests and should be used sparingly, use shutdown hooks or @PreDestroy for clean connection closure in Lambdas, GraalVM shines in CLI tools and polyglot applications, simple export method for Java version management, JavaFX on mobile is challenging but viable with Gluon, EJBs and some Java EE concepts are outdated, but interceptors and dependency injection are still relevant"

...is ready to watch:

See you every first Monday of the month at https://airhacks.tv 8pm CET (UTC+1:00). Show is also announced at: meetup.com/airhacks.

1. performance: abstract class vs. interface Hi, I got an interview question as to which one is faster Abstract class or Interface ? Can you explain please. What is Faster: String.join or Collectors.joining?
2. DB connections and lambda shutdown
3. performance measurement with or without JMH: "PLEASE use the microbenchmark harness in future videos. I have the impression, that this suggests that performance measurements with after-minus-before is a good idea." from: What is Faster: String.join or Collectors.joining?
4. the 100-episodes back time machine. Questions from: 27th airhacks.tv:

   "Interceptors and Dependency Injection Singleton EJBs, CDI and concurrency BCE in Eclipse and can Boundary communicate with Entity? Stateful EJBs vs. SessionScoped"
